    "\n",
    "Python是一种简单和强大的编程语言。说它简单，我的意思是它比C这样的语言更为宽容，尽管C速度也很慢。说它强大，我的意思是它可以像胶水一样，很容易地将许多用C、C++、Fortran等语言编写的代码粘连起来。Python程序包是Python代码的主要主机(宿主)，已经列出了超过15,000个包，说明了它的受欢迎程度。与其他领域相比，在水文学社区使用Python并不那么快，但现在，许多新的水文程序包正在开发中。Python提供了GIS工具、数学、统计等的良好组合，使其成为水文学家的有用语言。以下是Python对水文学家的主要优势：\n",

    "- 1.清晰易读的语法。\n",
    "- 2.模块可以很容易地用C，C++编写。\n",
    "- 3.可以在所有主流平台(Windows,Linux/Uinx，Mac等)上使用。\n",
    "- 4.易于学习。\n",
    "- 5.而且是免费的。"
